4To allfwhom it may concern Beit known that I, CHABLIS H. Cnowm., a citizen of the United States, and resident of the borough of Brookl in, county of Kings, city vand State of ew York, have made a certain new and useful invention relating to Tape Moistening and Severing Machines, of which the following is a specification, taken in connection with the accom-l pan ing drawing.

T is invention relates especially to machines for severing and moistening gummed tape or printed labels which may be made u in perforated strips in roll form forapplication to packages or' articles. One or more rolls of such perforated paper or cloth tape which may be previously gummed may be'arranged on the machine and a strip from each roll may be led into engagement with a feed roll, the operation of which is manually controlled so that it is only intermittently operated when the perforated labels or strip material is to be fed forward over the feed table. Beyond this feed roll a continuously operating pulling or severing roll may be arranged to feed forward the strip and to sever the same at the adjacent line of perforations when the feed roll stops. The severing roll or other device may be arranged in connection with a moistening or gumming roll to render the strip material or printed label adhesive before it is delivered upon a corrugated or other delivery table, for example.

In the accompanying drawing showing in a somewhat diagrammatic way illustrative embodiments of this invention,

Fig. 7 -is a detailed sectional view showing another form of construction.

The machine may be provided with a standard or base 1 to which the side plates or frame members 2 may be secured in any desired way. An outer removable frame member 3 may, if desired, be vsuitably connected to the base or adjacent frame member and assist in supporting the elements and moving parts, such as the shaft or support .26 on which the one or more supply rolls 25 of tape or labels may be arranged and supported. A number of such supply rolls of perforated gummed tape or labels may be supported side by side and preferably separated by intermedia-te spacing disks or members 24, suitable end plates 27, 28, being preferably mounted on the support so as to yieldingly press the rolls together by the action of the Spring 29 when the set screw 30 in the hub of the plate 27 has been adjusted. In this way as many as four or more strips of such gummed or ungummed tape or perforated labels may be led through the machine and severed along such perforated lines of .severance as 83 so as to form separate printed labels or tape strips for application to packages.l The moving parts of the machine may be operated in any desired way and for some purposes it is advantageous to have an electric or other motor 4 mounted in any convenient position on the base of the machine and as indicated this motor may have its pulley 5 connected f by the belt 6 with the drive pulley 7 on the drive yshaft 85.

The tape strips may be led along the feed table 82 and beneath the guide roll or device 23-so as to be engagedby a feed roll such as 18, which may be mounted to cooperate with this feed table and feed the strips along the same in connection, if desired, with a feed presser 31 which may be yieldingly forced against the feed roll and be provided with a rubber or other yielding face 32. This presser may have its shaft mounted in the arms 19 secured to the rock shaft 20 and the releasing lever 22 may be connected to one of these arms and normall actuated by the spring 21 to force this flied reer against the feed roll and ensure t e proper grip upon the paper strips. This feed roll which may be mounted on the feed shaft 15 is preferably intermittently power operated or controlled in its operation so as to feed forward one or more strips. This may be effectively accomplished by having a slip friction clutchbetween this roll'and its driving devices and by positivel stopping. the roll at the desired inthe individual printe or other perforated labels or strips being handled. In order tomaketheopeiationofthisfeedroll adjustable to suit different lengths of labels or strips change may be introduced between the sto n and the roll shfo d one convenient form ofmechanim r p may comprise -the drive pinion 8 on als drive shaft 85 as shown-in Fig. 3 which may mesh with Ayieldahle friction or slip clutch d s m disdmbd lsi in 6 ma on Y andFlgoiced {ogetheras by the adjusting nuts 95 so that normally the feed gear 11 1s rotatedinunisonwiththegear9 butslipping of this 11 can take place about the drive sha when its rotation is interrupted. Any suitable change may be usedbetweenthisfeedgearll andthe feed ge shaft 15, and, for example, the change gears .12, 13 may rotate er about the stub diaft 4:9 adjnstably supported in the sector slot 94 so as to be rotated by the feed gear, thegear 13 meshing with the feed. pinion 14 on the feed shaft 15. YBy rtelpelacing one or more of these change gears ratio be tween the feed gear 11 and the feed pinion and feed shaft may be within considerable limits so that diiferent lengths of labels or tape strips may be supp 'ed' by the machine. desired, the

Ofcourse,if

feed presser roll 31 may be rotated in uni son with the feed roll 18 by suitable meshing gears 16, 17 on their shafts as shown in Fig. 5.

A convenient stop device for controlliiig the mechanical rotation of the feed roll may comprise a control wheel or stop disk 33 which ma be removably mounted on the drive sha k54 {and rotated in unison with the feed r 11 by any suitable connection such as e pins 91 on the feed gear which may have ends fi within the holes 90 intli'isstopdisk,as ownin 2. One or more stop members or rejections, such as34,35maybea ontheseinterchangeable stop disks and one, two or more such stop members ma be formed on each disk so that by intere g them astill further range of tape or bel length may be readily secured. .A detent device of any suitable character may cooperate with this stop diskto restrain its normal tendency to rotate as long as the motor is in operation, and the pivoted control device or detent 36 maybe arranged as indicated in Fig. 2 so that this spring actuated member may have its projecting detent 86 normally in the path of the stop member 34 on the control wheel 33, while the actuating handle or lever 39 pivoted about the pin 40 may be manually depressed so as to move the connected actuating link 38 and swing this ontuol device about its pivot 37 so as to G5 remove this detent from the path of the devices for the feed roll 9cmthe'iiiaiiishaftiof'thema-A sensei A throws the detent 86 out of engagement 75 with vthe stop member throws another detent 87- into the path ofthese stop members so that the succeeding stop member engages this detent and its movement is Ainteri'u ted if the actuat handle is kept au in its epressed position. en this actuating handle is released the detent instantly returns to its normal position shown in 2 through the action of these parts and t e'restoring spring on the detent; In this way by the use of the desired disk and the change gears between the feed gear and the feed shaft a single movement of the actuating lever( or handle allows the feed roll to revolve to such extent as to feed so forward a single length of the perforated tape or strip between the .lines of perforation or other weakening 83, 83', as shown in Fig. 5, which may bel reviously formed in the paper strips. Suc an intermittent fee device ma of course be advantageously used to eed forward adjustable length pieces of unsevered tape in connection with various forms of severing and moistening mechanism. 1 100 The severance, delivery and' moistening of each, successive label or perforated strip length may be conveniently effected by contlnuously operating, pulling, severing or moistening rolls or devices adapted to engage each successive length of strip supplied y the feed roll and pull it forward and sever it and meisten or the strip and deliver the same for app ication to a package. For this pur suitable pulling or severing rolls or evices may be continuously operated in any desired way as by connecting or gearing them to the moto'r or driving connection of the machine and as shown in Fig. 1 the rubber or other pulling roll 57 may be mounted adjacent and ahead of Athe feed roll 18 and may, if desired', have e. cooperatingpulling presser roll 58 mounted in arms 59 normally actuated by springssuch as 60 to swing them about the pins 61 and maintain the desired engagement between these cooperating presser rolls, Awhich may be geared together as by glie gears 55, 56 on their shafts as shown in The moistcning device which may be of any suimble construction may comprise the moistener roll 67 which may as indicated in Fig. 6 be formed with longitudinal corrugations and also, if desired, with annular 130 rees 66 with which may cooperate stripper blades or knives 74 yieldingly mounted on the bar 73 to disengage the paper strips from the moistener. A mostening preer roll, such as 68, may bel formed with separated annular ribs 69 and be mounted 1n rock arms 70 supported by the pins 71 while the rings 72 normally force this presser roll lbw-n upon the paper strip or on the moistener roll beneath when the strip is not interposed. The moistenin'g or gumming material maybe. sup) lied to this- Ymeisteng ing roll in any suita e way as through the water roll 65 of metal or other suitable materialwhich may be mounted -on the shaft 48 so as to rotate within the tank 75' and carry up to the moistener water or other li uid 76 from this tank. These rolls may all be positively driven from the drive gear of the machine, if desired, and for` this purpose as indicated in Fig. 3, the shaft 48 of the water roll may be providedI with a gear 45 with which the gear 43 may mesh and be engaged by a change gear 42 on the adjustable stub' shaft 50 mounted within the slot 51'and also supporting the gear 41 rotating in unison'with the gear 42 and meshing with the r 9 on the main shaft 54. The shaft46 on which the `pulling` roll 57 -is mounted may be provided with a pinion 44 meshing with the .gear 43 and as shown in Fig. 6 the gears 62, 63 and 64 may drive the moistening and` cooperating presser rolls from the water roll, 1f desired. In this wa the motor of the machine may continuo y operate the pulling and meistening rolls while the slip clutch connection between the feed roll and its gearing makes it possible to'restrain the normal tendency of this gearing to operate lthe feed roll except when the actuating handle or lever is moved by the operator. Under these circumstances the feed roll rotates through a suicient distance to feed forward a length of tape so that as indicated in Fig. 5 the end 83 of each label or tape strip may be fed forward' until the line of severance 83 arrives at substantially this same position. In the meantime the pulling and moistening rolls which may sometimes be slightly underspeeded so that as soon as they engage the tape strips they pull the same forward at a slightly reduced rate, continue to operate after the feed roll stops, and this further rotation of the pulling rolls exerts suilicient tension on the tape strips so that they are pulled apart or severed along their weakened portions or lines of severance, as for example, between the printed labels on the strips. In this way accurate severance of the labels is always secured even when because of slight irregularity of feeding and so forth, the ends of these tape strips move forward or backward slightly from the predetermined or pulling the mid position between the feed roll and roll. There is thus no substantial danger that impro r severance will occur and of course 1f or any reason such as wearing of the feed roll or slipping thereof, the tape ends get too far out of the desired alignment, they can be manually adjusted asmdicated in Fig. 7 by releasing the feed presser roll 31 and manually pushing forward or backward one or lmore of the tape ends. F ig. 7 also indicates a desirable variation in this device which may be effected by spacing the pulling and -moistenmg rolls somewhat more closely together so that still shorter lengths of gummed labels or tape strips may be handled effectively by the machine. After severance Iand moistening of thefstrips they may, if desired, be separated from the moistening roll by the spring pressed or yieldable @ripper blades 74 resillently held down on the moistening roll 67 as by the spring 77 and guided out on Ia delivery table 78 which may be adjustably or removably secured to the frame members as b the bolts 80 shown in Figs. 1 and 5 which may clamp the depending flange 79 of this table to the machine frame.

This delivery table may advantageously be formed with narrow upstanding longitudinal ribs 81 tominimize contact between ed or adhesive side of the tape or labe which ma the operator and, articles. As shown 1n Fig. 5 four such label strips may be simultaneously fed forward everyI time the actuating handle 39 is operated so that four gummed strips or labels are thus delivered on the delivery table to be yapplied vto packagesof such character as to need four securmg labels or sealing members. If desired, of course, a less number of supply rolls of wider tape or labels may be used in the machine and if it is desired' to handle different packages one or more of th'ese label strips may be manually withdraw-n from the feed roll so as not to be fed forward thereby so that the machine may be very readily and quickly converted to deliver a greater or less number of strips within the limits of its capacity.
